Commit 7f107887 ("ARM: dts: imx: Remove skeleton.dtsi") causes boot
issues when the bootloader does not create a 'chosen' node if such node
is not present in the dtb.

The reason for the boot failure is well explained by Javier Martinez
Canillas: "the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info."

, so pass an empty 'chosen' node to fix the boot problem.

This issue has been seen in the kernelci reports with Barebox as
bootloader.

Also pass the 'memory' node in order to fix boot issues on the SolidRun
iMX6 platforms.

This patch enables the DCP crypto functionality on imx28.
Currently, only aes-128-cbc is supported.
Moreover, the dcpboot misc-device, which is used by Freescale's
SDK tools and uses a non-software-readable OTP-key, is added.

Changes of v2:
- ring buffer for hardware-descriptors
- use of ablkcipher walk
- OTP key encryption/decryption via misc-device
  (compatible to Freescale-SDK)
- overall cleanup

The DCP is also capable of sha1/sha256 but I won't be able to add
that anytime soon.
Tested with built-in runtime-self-test, tcrypt and openssl via
cryptodev 1.6 on imx28-evk and a custom built imx28-board.
